“…A strategy involving the coupling of two semiconductors is an approach that incorporates metal oxides, typically in the form of MxOy/MezOt (where M and Me represent different metal types and x, y, z, and t denote their respective oxidation states within these metal oxides) [86]. This combination of materials, known as a nanocomposite, offers certain advantages, particularly in photocatalytic applications, due to its enhanced light absorption, effective suppression of the recombination of photo-induced electron-hole pairs, and improved charge separation.…”

Nanostructured metal oxide semiconductors have emerged as promising nanoscale photocatalysts due to their excellent photosensitivity, chemical stability, non-toxicity, and biocompatibility. Enhancing the photocatalytic activity of metal oxide is critical in improving their efficiency in radical ion production upon optical exposure for various applications. Therefore, this review paper provides an in-depth analysis of the photocatalytic activity of nanostructured metal oxides, including the photocatalytic mechanism, factors affecting the photocatalytic efficiency, and approaches taken to boost the photocatalytic performance through structure or material modifications. This paper also highlights an overview of the recent applications and discusses the recent advancement of ZnO-based nanocomposite as a promising photocatalytic material for environmental remediation, energy conversion, and biomedical applications.
